Application inea october 4,1926.v serial NoQieeAoi.

-l This .invention relates to' a detachable trunk forautomobiles and ithas for its object to provide a trunk like container having meansmounted thereon tor easily and quickly attaching: thesaid containertothe sparetire carrierring` orto the rim `of a spare tire 4of anautomobile. IItis quite com-v Y mon to mount trunks and like containers`'upon` the rear of automobiles. l()

i However, many automobiles arenot equipped to receive trunksvas a partot theiry regular equipment. and, asra matter otfact. it is neither.v

necessary nor desirable tocarry thesetrunks about. inr ordinary. abouttoivn.. driving. However;Whentouring, or ivhen on picnic trips. theseltrunks become desirable and it-is the purpose ot' the. present inventionto provide means whereby theyrmay be readilyA '2 attached when required.

The trunk 9, having` the usualfastening devices '10 and 11. will, preferably. be made ot very Upon itsrear side, this trunk-carries bearing brackets 12, 12a and 13.132` inwhichr rack bars 14 and 15 are mounted for slidable movement. torni ofthe invention illustrated in Figs. 1. 2 and 3. keach rack bears a pairofccurved Vfingers 16, which, when the rack` bars are projected orvmoved outwardly with respect to each other, engage over the inner faceof the spare tirevrim 7 vorthe Spare tire carand 15 l ,in` lieu. oi the`double hooks previously described. though it-is, of course, manifestthat VIn the rier ring` 5l. as the case may be. That is,

`whenv the sparc tire carrier comprises acomplete circular ring 8, whichlies inthe path j ot inoveiiricnt ot the said hooks, then the hooksengage that ring.` but thereare Some rypes spare tire carriers onthemarket 4which consist merely of a plurality of radial arms in that case,the tire rim 7, itself,

vwould be. opposed to the hooks and Vwould ,Vlie engaged by said hooks.'However, the

andi/23 andfheingprovided with a handle 2li-bv which it may be turned.It isvclear that if.' the vertical Vshaft is Vturned in one direction.the bars'lli and 15` Willbe moved inwardly. while it' the shaft beturnedin the other direction, the said bars Willbe moved outwardly or toprojected Vposition and when in the latter posit-ion. the Fingers 1.6and 16"L will act to engage the 'spare tire carrier ring, orthe Sparetire rim in so `forcible a manner as to very firmly mount thistrunk invplace. It contemplated that. the fingers 16 andV 16' mar he. ,ifdesired. ot resilient `material so elasticity whereby all tendency ofthe parts to rattle or squeak under the movement of' thefvchicle. willbe eliminated.

their engagement l, will be of some In 'thefoim ot" the v.inventionillustrated in spare tire rim to support. part ofthe-weight oil' thetrunk. Inv this case the rackbars '14 are j provided with single hooks*16",

double hooksv maybe usedmin this relation,

In F 5.a locking means for the verticalk shaftis illustrated whichserves to hold the rack bars in their projected positions. Thislocking): meansy comprises a `keyway 24,

formed in the vertical'shaft 21. awplurality of complemental openings25. "t'ormed in the.' upper hearing' bracket 22 and a removable' pinQG.constitutingr a key cooperating with` openings 24 and 25V to lock the`shaft against movement with respect tothe bracket, after the rackars'have been` projected to their maximum,locking position. 4 Fig'. 6illustratesa modified form of rackA CII or toothed bar in which thefingers 16C are Curved inwardlyv instead ot outwardly1 as in the otherfigures. By modifying' the shape ot the hooks as suggested in Fig. 6 andmaking the rack hars of Sufficient length, the Structure could he madeto `efrip the outer tace ot the spare tire itsel't instead ot' thespare. tire rim or carrier. lt is manifest that in this` case thegripping action would be eii'eeted hy inward movement of the rack hars.

It is to he understood t-hat the invention is not limited to the preciseconstruction set forth but that it includes within its purview whateverchanges fairly come within either the terms or the spirit ot' theappended claims.

Having; descrihed the invention what is claimed is:

l. The combination with a trunk or like` container. ot eomplementalgripping means movable hack and liorth across the rear tace thereot andhaving parte projecting perpendicularlv to the hack ot the trunk adaptedto engage the spare tire structure of an automobile at :substantiallyvopposed dialnetrie points ot the latter.

Q. The combination with a trunk or like structure. ot gripping meansmovahle inwardl)7 and outwardl)7 at the rear vtace thereo't' and havingvparte projecting perpendicularly to the hack ot the trunk. adapted whenprojected out 'ardly to engage the inner Jr'ace ot the spare tirestructure ot an automobile at substantiallyY opposed dialnet-rie pointsot lthe latter.

3. The combination with a trunk or like container. ot a pair ot rackhars mounted upon the rear face thereot. a vertical shaft carrying apinion engageahle with said rack hars tor projecting and retractingrthem and means carried h'v the outer ends ot said rack hars projecting'perpendicularlif' to the hack of the trunk to extend within and engageover the inner tace ot the spare tire structure ot an automobile atsuhstantialh` opposed diametricA points ot the latter.

4. A structure as recited in claim 3 in comhination with locking meansto prevent reverae movement ot' the rack bars,

5. A structure as recited in claim 3 in combination with a locking'means tor the vertical shaft.

ti. A Structure as recited in claim o in comlinnation with a removahlelockn'ie pin l'or 4tace ot' the Spare tire struct ure ot an automohileat snhstantially opposed dialnet ric points ot the latter. a pinionengaging" said rack 1oars and means ior operating` .said pinion.

8. The c omhination with a trunk or like container having a length inexcess ot the diameter oi: a tire carrier. ot a pair ol' ele.- mentsmounted upon the rear tace thereof. niemhers movahle toward and l'romthe ends ot said trunk. carried hv the first named memhers and shaped toproject within and engage over the 'faces oli the spare tire .structureot an automohile at' uhstantiallv opposed diametric points ot thelatter. means tor moving' Said lirst named memlwr.`-l toward and 'fromeach othe and a supportilmv memhcr at the hottom ot the trunk. adaptedto engage over the lower central portion ol` the spare tire structureot' the automohilc.

S). The coml'iination ot' n trunk or like container` a pair ol rack harsupon thc rear face, thereof. fingers, a t the outer ende' ot' said rackliars shaped. to ennan'e thc .spare tire. structure of an automohile avertical .shaft carrying' a pinion enqjan'eahle with said rack liars. anoperating' handle upon the upper end ot said vertical shal't. l-.earine'liratlcets 'for the upper and lower portions olI said shaft and hookedsupportingA tincgers projected trom the lower hearing lirorlict andadapted to engage over the lower central portion of the spare tirestructure ot the automobile.
